LOINC display name : TRBV4 gene segments/TRBV gene segments.total (Bld);
LOINC long common name : TRBV4 gene segments/TRBV gene segments.total in Blood;
LOINC short name : TRBV4 seg/TRBV seg total NFr Bld;
LOINC description : This assay represents the fraction of T-cell receptor beta chain variable gene segments
that are in the TRBV4 gene family out of the total number of TRBV gene segments identified
(diversity ratio). At the time this term was created, TRBV4 included the following
gene segments: TRBV4-1, TRBV4-2, and TRBV4-3. Because some portion of TRBV gene segments
that are counted in the total will not correspond to any of the probes and therefore
will not be identified as belonging to a specific TRBV gene family, the total of the
diversity ratios reported will not equal 100%.;
